SILYLATED POLYETHERS

摘要

Silylated polyethers having the general formula: wherein at least one R is selected from the group consisting of an -NH radical, an ammonium radical or a radical of the formula in which the radicals are linked to the polyether through an ester, amine, amide or ammonium radical and the remaining R groups are selected from hydrocarbonoxy radicals having up to 18 carbon atoms, hydroxyl radicals or a radical of the formula R1 is a divalent hydrocarbon radical selected from the group consisting of -(CH2)y, -CH=CH-, or a cyclic radical selected from the group consisting of C6H4, C6H8 and C10H6; A is a silicon containing radical selected from the group consisting of cationic or anionic radicals of the formula or and nonionic radicals of the formula wherein R2 and R3 which may be the same or different, are monovalent hydrocarbon radicals having from 1 to 18 carbon atoms, R4 is an ionic radical linked to a silicon atom consisting of hydrogen, carbon, oxygen and nitrogen atoms selected from the formulas +TR in which R5 is a nonionic radical consisting of carbon, hydrogen, oxygen and nitrogen atoms selected from the formulas +TR and when R is an -NH radical, then R5 may be a divalent hydrocarbon radical and R6 is a radical having from 1 to 10 carbon atoms selected from the group consisting of a saturated divalent hydrocarbon radical, a divalent hydrocarbonoxy radical in which the oxygen is in the form of an ether linkage and an unsaturated divalent hydrocarbon radical in which the unsatisfied valences are linked to a silicon atom, and when R is cationic, then A must be anionic, and when R is anionic, then A must be cationic and when R is nonionic then A must be nonionic, a is a number of from 0 to 4, b, c and d are each numbers of from 0 to 1, the sum of b, c and d must be 1 when A is a monovalent radical and 0.5 when A is a divalent radical and when b, c or d are O, then R must be a hydroxyl or hydrocarbonoxy radical or a radical of the formula e is a number of from O to 2, n is 2, 3 or 4, x is a number of at least 1 and up to 600, preferably from 10 to 250 and y is a number of from 0 to 8. These silylated polyethers may be used to treat textile materials to impart hydrophilic finishes thereon.
